When I owned my Corvettes, other owners would always wave. What I have found with the Crossfire is that other owners refuse to acknowledge that you even exist. A recent trip to Daytona was proof enough when I was sitting at a stop light beside another Crossfire and I did everything but knock on her window without so much as an acknowledgement (this actually happened twice with two different Crossfires). I've only had one other owner wave and he was from SC cruising down I95 in Georgia. Guess we are an elite bunch that are above that sort of thing! I always thought it was one of the cool things about owning a 'Vette but it doesn't work with the Crossfire.
